Preheat oven to 180°C (350°F). Cut potatoes lengthways into quarters and place in a bowl of cold water. Rinse under cold
running water and pat completely dry with absorbent kitchen paper.
Arrange them in a shallow baking dish; add the olive oil, rosemary, salt and wine. Bake in oven for about 40 minutes, or until golden
brown and tender, stirring.
Sprinkle with paprika or pepper or chilli.
